2. 2 Reliability & Availability Defect Prevention and Elimination Quality Life Cycle of a Product Useful Life Integration, Deployment & Early Life Supplied Materials & Parts ManufactureDesign End of Service

3. 3 Product Failure Rate Over Time: Early Life Failures and the Bathtub Curve Early Life Failures Steady State Wear-out

4. 4 Product Return Rate Trend Early Life Failures and Possible Design or Materials Problems Exposed Escaping Defects, Integration and Application Problems Stable Operating Period Wear-out Phase is well beyond this time scale

5. 5 Product Availability Calculation

6. 6 Statistical Process Control (SPC) Process characteristics and outcomes contain variability over time. Process characteristics and outcomes contain variability over time. Statistical Process Control is used to Statistical Process Control is used to Track the process variation, Track the process variation, Determine the current amount of expected variation, Determine the current amount of expected variation, Identify when the variation exceeds statistical limits, Identify when the variation exceeds statistical limits, Provide insight into how to reduce the process variation, thus increasing the process capability (Cp) Provide insight into how to reduce the process variation, thus increasing the process capability (Cp) SPC control charts show the tracked values and statistical limits SPC control charts show the tracked values and statistical limits Goal is to stay inside the limits and to reduce the limits by continuously decreasing variability Goal is to stay inside the limits and to reduce the limits by continuously decreasing variability
